Radio frequency radiation occurs at the low end of the electromagnetic spectrum. It is comprised of long wavelengths of radiation energy, and is thought to be relatively harmless to humans. As a result, it is used in a variety of appliances and electronic equipment. The radiation emission is relatively small, although scientists have not yet determined whether it is entirely innocuous.

How Low Can You Go?

The electromagnetic spectrum encompasses the full continuum of energy wavelengths. Thus, it includes everything from very low-frequency waves to the extremely high frequency waves such as x-rays and gamma rays. The spectrum is broken down into seven categories, and radio waves are considered the most innocuous class on the continuum.

Radio waves are generally defined as being low frequency and low energy, but long in wavelength. However, according to NASA scientists, there is a good deal of variability even within this class on the spectrum. Most of us think of radio waves as vehicles for producing sound from our stereo systems. Although this is certainly true, they also do a good deal more.

Radio waves are also produced by stars and by certain interstellar gases. They are also produced by televisions and by certain types of tracking devices. Despite this variability, all radio waves are considered to fall at the low end of the EMF spectrum, producing less radiation than your average microwave. This relatively safe emission level makes them a popular source of energy for a wide variety of electrical and mechanical appliances.
